Make aggregate.create() and destroy() use the API rather than cell database.
Also block aggregate creation until main database empty. This makes
Aggregate.create() fail until the main database has had all of its aggreagtes
migrated. Since we want to avoid any overlap or clashes in integer ids we
need to enforce this.
Note that this includes a change to a notification sample, which encodes
the function and module of a sample exception (which happens to be during
an aggregate operation). Since the notifications are encoding internal
function names, which can and will change over time, this is an expected
change.
